in the" construction, combination and arrangement of'the various parts of the device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which,

Figure 1 shows .a top orplan view of a plow, .embodying my invention,-in which a plurality of reversible plows are mounted on a frame, parts being omitted for clearsectionalview of my improved plow frame used the reference character 88' to indicate the beams of plows. Secured to the lower rear members of beams 88 are the forwardlyextending members 12.- On each side of.

each member 12 is a plate 13. Plates13 are designed to serve as land sides depending upon the position of the reversible parts of the plow.

Fig. 2 shows a side elevationof the F 1g. 8 shows a rear elevatlon' of the same Fig. i shows a transverse,'vertlcal,

Mounted in the rear lower 'portaken on a lmem front of the hand steering wheel. Figs. 5 and 6 show detail, sectional" tion of each beam 88 is a shaft l l which versible plows mounted upona frame and providedwith suitable mechanism, which will now be described. I provide a triangular frame comprising side members 45 andthe transverse member 4.6 which is at the forward end of the ma: j

chine. The apex of the triangular frame is at the rear of the machine as shown in Fig. 1. At the rear of the machine I provide an upright shaft 47 having at itsiupper end a sleeve 48, in which said shaft rotates freely.

* Slidably mounted on the shaft 47 below the sleeve 48 is the collar 49 which may be fixed upon the shaft 417 in any position by means of the set screw 50. The rear ends of the I land as shown in Fig. 3.

10 forth, and on account of the construction of the. spindle is always inclined upwardly and slightlytoward the middle of the machine. This construction is adopted so that thewheel 52 will lean away from the plowed Atthe forward end of each frame45 at each corner thereof is an upright shaft 53, having at its lower end an extension 54 extending outwardly and. preferably slightly downwardly as shown. in Fig. 3. The. extensions 54 form spindles for the front wheels 55 on which the main frame is supported. On the upper ends of the shafts 53 are sleev'es 56 in which the shafts 53 rotate freely. On each shaft 53 below sleeve 56- is a collar 57 which may be fixed in anyposition, on the shaft 53 by means of a set screw 58. The frame members 45 are pivoted to the sleeve 56 to permit said frame members a certain degree of pivotal movement in vertical planes. The

. transverse frame member 46 is pivoted at its ends "to the sleeves 56 to permit similarly pivotal movement. Nearthe lower ends of the shafts 53 I provide collars 59' slidably 85 but non rotatably mounted on said shafts.

A second frame comprises transverse end members 60, side members 61 and 63, middle member 62 and spaced intermediate longitudinal members 64 and 65, members 64 and l 6'1being preferably formed of channel bars opening towardeach other and the members 65 and 63 are madeof similarly arranged channel bars'as shown in section in Fig. 4. Extending laterally from the forward end 'of the second frame are laterally extending arms 66, having at their outer ends sleeves 67, slidably mounted on the shafts 53, on.

the sleeves .67 are secured downwardly extending arms 68 for supporting the collars 958 and causing them to move upwardly or. downwardly with the sleeves 67. Extending rearwardly from the rear transverse' frame 'member is'a bracket 69 on which is formed a sleeve 70 in which the shaft 47 is 55' rotatably mounted. iRotatably mounted in the longitudinal member 62 at'the forward end thereof is an upright shaft 71. Fixed on the lowerend thereof is the collar 59*. Formed on and extending forwardly from Q: the collar 59 is an arm 72 which is pivoted j at its forward-end to the transverse bar 7 3. Formed on and extending forwardly from .the collars 59 are arms .72, which are pivoted at their forward ends tofthe bar 73.

( Secured to the forward transverse member carry the plows.

ing shown in Figs. 2 and 8, each of which is pivoted at its forward end to a'transverse draw bar 75 to which the double trees or evener bars may be secured. Slidably mounted on the upper end of theshaft-71 is a sleeve 76 which is pivoted to the transverse member,46 of the flexible frame. I provide 60, are forwardly extending brackets 74 bea-tongu'e 77 the rear end of which is pivoted toswing vertically in a bracket 7 8-having rearwardly extending-bifurcated arms 79 spaced from each other in a vertical plane, which are slidably but non rotatably mounted on the shaft 71 above and below the sleeve is a drivers seat 80'. v

The second frame is designed to be main tained in a substantial level position and to 76. Suitably supported on the second frame frame upwardly or downwardly on the shafts 47 and 53- and thereby maintaining it in a level position regardless of whether. or

For sliding thefsecond not one of the wheels 53 and thewheel 52" are traveling in the furrow, I haveprovided the following mechanism. Fixed on the sleeve 48 is a sector 81. Pivoted to the sleeve 48 is a lever 82 provided with the ordinary spring. actuated pawl for coacting with said sector. Pivoted to said lever 82 and to the rear transverse member 60 is a link 83. It will be seen that bylowering or raising the lever 82 the rear portion of plow carrying frame may-be raised or lowered on the shaft 47. lMounted on the-frame members 45 are sectors 84. -Pivotally, supported; on. the

frame member 85, adjat ent to sctors 74 are 1 One arm 85 of-eachibell bell crank levers. cranklever is extended to form a lever arm on which'ismounted an ordinary spring ac- ,tuate'd pawl, designed to coact with the adj a centsector 84. The other arm 86 of.each

bell crank lever is pivoted to the link '87, the lower end of which is in turn pivoted to a lug extending upwardly from'the arms .66.

It will therefore'be seen that by raising or' lowering the levers 85 respectively either.

side ofthe forward end of the plow carrying frame may beraised or lowered -with relation to one of. the shafts 53. I

Where the plurality of reverse plows are used in connection with the frames as here inbefore described the plows are built as above described. Slidably mounted between [the members 61 and 64 are blocksg89 to which the beams 88 are secured. ,Slidably mountcarrying frame. The middle plow is ap-.

proximately located in the middle of the frame by bolts 62 as shown in Figs. 1 and 2 with the beam 88 secured to the longit'udi 2o ed between the members 63 and 65 are simi nal member 62. The beam of the right hand I reversible plow is secured to the blocks 89 and the beam of the left hand plow is secured to the blocks 90. It will already be understood that where plows are,v used in gangs they are arranged in successionyeach' plow being in .the rear of the one preceding it and also spaced apart therefrom laterally as shown in Fig. 1. In order to use re'- versible plows'of the type herein set forth, in gangs it is necessary to change the position of some of the plows in. relation to theback without going around the land and the left hand plow.

plows are reversed, it is necessary to shift the positions of the right and the left hands of the" plows so that the left hand plow willbe in front of the middle plow and,

spaced apart therefrom upon the left side thereof, and the right hand plow will be in the rear of the middle plow and on the right side thereof.

For shifting the position of the right and left hand plows as just described l have provided the following mechanism. Mounted in the plow carrying frame at the forwardend'thereof between the members-61 and 6 1 and between the members 65 and 63 are sprocket wheels 92 mounted upon said frame. Mounted upon said frame in relation similar to the position at the rear end of the frame are sprockets 93. Secured to the block 89 at the forward end of the beam 88 of the right hand plow is a sprocket chain 941- which is extended around the sprockets 92 and is secured tocthe block 90 at the forward end of the beam 88 of the I Asimilar sprocket chain 95 is secured to the rearward of the blocks 89 and 90-and extends around the sprockets 93. For operating the sprocket chains and the blocks 89 and 90 and thereby shifting the position of the right and left hand plows, I,

have provided the following means: Mounted in the forward transverse members 60 is a'short upright shaft 96 on which is a sprocket 97 shown inFigs. 7 and 9 in mesh in the sprocket chain 94 Upon the upper end of the shaft 96-is fixed a beveled gear 98. Rotatably mounted in suitable bearings and extending upwardly and rearwardly from the forward end of the machine is a shaft 99, on the lower end of which is a beveled gear 100. in mesh with the beveled gear 98. On the upper end of the shaft 99 isa hand wheel 101. For locking the beams 88 of the right and left hand plows in either of their shifted positions 1 have Provided the following means: In the upper surfaces of said beams 88 near the forward and near the .dinal axis of the machine.

rearward ends thereof I have providednotches 102. 'Rotatably mounted in suitable bearings 103 preferably on the transverse member 91 isa shaft 10-1 on which is a foot lever 105 which is yieldingly held at the of a contractible coiled spring. 106 whichiis secured to the link 107 mounted on the shaft 104 and to the plow carrying frame as shown in Fig. '1. At each end of the shaft 104 is a forwardly extending arm 108 on the forward end of which is a downwardly extending catch device 109 clearly shown in Fig. 5. The portion 108 normally rests upon thetransverse member 91 as shown in Figs. 1 and 5. When the'beams-88 are moved to position with one ofthe notches 102 below the catch device 109 and the lever 105 is released said catch device will. enter said notches and hold said beams against rearward movement. a

It will be noted that the tongue 77 is fixed to the bracket 7 8 so that when said tongue is turned in turning the machine the shaft 71 will be slightly rotated. The rotation of the shaft 71 through the collars 59, the arms T2 and the cross bar 73 causes the wheels 55 to turn laterally with the tongue for turning the-machine. In order to turn the wheel 52 at the same time and also for swinging the wheel 52 around from its position as shown "in Fig. 1 with the extension 51 extending upward position of its movement by means..

laterally toward the left side of the machine i at right angles to the shaft 47 to position where said extension extends inthe opposite direction I have provided the following means: Fixed upon the shaft 71 is an arm 110 arranged at right angles to the longitu- Fixed to the shaft 5 .7 is a similar arm 111 which extends away from the shaft 47 at an acute angle from the longitudinal axis of the machine so that the distance between the endsof the arms 110 and 111 will be the same regardless of the position of the wheel 52. Pivoted to the arm 11-0 is a link 112 which extends rearwardlyinto the machine and is received-in the sleeve 113. Pivoted to the arm 111 is -a forwardly extending link .114 the forward end of which is telescopically received in the sleeve 113. Suitably mounted onthe sleeve 113 in the positionwhere it is convenient of access is a sp-ring controlled foot lever 115 having a catch device 116 formed on one end and designed to be received in suitable notches in the sleeve 113 and link 11% whereby said sleeve and said link may be locked together as shown in Fig. 6.

For turning the wheel 52 from one position to the other as hereinbefore mentioned 1. have provided the following means: Mounted on theshaft 17 is a gear wheel 116. Mounted upon the plow carrying frame is a guide device 117 carrying a rack bar 118 the teeth of which are in mesh with the rack bar controlled by a lever 120 whichmay be.

teeth. ofthe gear 116. Connected with the is' a forwardly'extending link "119 mounted upon the frame member 91. Th

middle plow is reversed in the. following manner Pivoted to the-mar end of the beam 88 of the middleplow-is a lever 30. FiXed on the rear end of each shaft 1-1 isa lever 33.

- Pivotedv to the levers 33 are upwardly eX- tending-links The li-nk'84 ofthemiddle lever 30. l h ave provided for automatically reversing the right and left hand plows 'when'itheir positions are shifted iathe followingm'ranner': I provide T bars 121 mounteel r. the plow carrying frames Suitably by arranging the parts so that the plow carmounted upon said T- bars are arms 122" to one en'dof which is pivoted the link 34?. The T bars 121 are twisted as shown in Fig. 7 in such a mannerthat when=the right arid left hand plows are shifted the arms 122 will'be ,so' moved .as to cause the reversing of said plows In practicable operation of the plow shown in. thedrawings it has been improved rying" frame may always be substantially level f or thatireas'on I .have-slidably mounted it upon the shafts 53 and 47. In this connection it may benoted'that' the gear '116 and the-arm 111 are.'-capable of sli'dabl'e but not of'rotary'movement with relation tothe .shaft 17:. Assumingthat above frames are in substantially level positions and that the wheel 55 and the wheel 52 on one side of the machine are then'to travel on lower ground than the other wheel 55, then the lever 85 is used to raise the corner of the plow carrying frame which is low tothe proper level. The lever 82 may be used to raise the rear endof said frame.

' carrying frame is raised at theforward end with relation to one of the shafts 53 the re-. sult in the case assumed is that the plow carrying frame remains level .while one corner of the triangular frameis lower than the rest (if said frame-as shown in Figs. 2, 3

and 4. Assuming that the plows are set for turning a furrow to the right then when the' end of the field is reached the machinemay betuihed around,- the plow carrying frame I adjusted and theplows shifted andreversed:

l/Vhen the machine turns and the tongue-77 7 -is turned to an acute-angle with relation to the longitudinal axes of the .machin'e,'thereby slightly rotating shaft 71, the rotation of the shaft 71 through collars 59 and arms 72 and the cross bars 73 causes the shafts 53 to rotate slightly thereby turning the wheels 55 laterally for makingthe turn. The rotation of the shaft'71 through the'arms 110 and 111 and the mechanism connecting them causes a slight rotationof the shaft 17 for turning the wheel 52 to proper position for making the turn. \Vhen the turn has been is p ivo ted at its upper end to the 'be used for throwing the dirt in either direc- W'hen one corner of theplow 121 will cause the mold boards and shares of said'plows to be reversed. The foot lever 105 may be depressed during the operation of the hand wheel 101 and released whenthe' shift of the plows is completed thereby permitting the device 109 to enter the notches in the plow beams and securely lock the 1 plows against rearward movement. The middle plow may be reversed by theopera tion of the lever 30. The tongue is-attached to the upper end of the shaft 71 for the rea- -son that such an arrangement makes it easier to turn the machine.

' The advantages of myimprove'd plow are numerous. x

' With a device of this type,- the plow may .tion and the land may be plowed from one end of the plowed ground to. theother in the double urrow which is ordinarily produced'ca'n be avoided.

By means hereindescribeda plurality of my reversible,

. lows ma be mounted foruse in a an l P y g g 100 In using a plurality of reversible plows a number of difficulties must be metv and it has been my purpose to solve'these difiiculties by essary that the frame for carrying the plow should be substantially level. This I have accomplished by mounting said frame upon upright shafts. In addition to these I have provided a-flexible frame for carrying the levers and furnishing bearings for the upper ends of said shafts. The result is a very strong rigid machine. I have provided the stead of plowing around a land in the ordinary wa By using a plow of this type: l

'. Ina machine of this kindit is necessary that partof the plows be shifted as herein before set forth, and I have provided simpleyinexpensive and effective mechanism for accomplishing said .shift. In connection .with said means I have provided means for reversing the two out side plows by the same operation which shifts their position. I have "provided simple and efi'ective means for turning the wheels laterally when the machine isturned around. which means include mechanism for causing the rear wheelto turn laterally in unisonwith the front wheels. All of the controlling mechanism is thereon capable of forward and rearward of reversible plows may be used with my frame and shifting and reversing mechanism .but I have described a reversible plow with suliicient fullness to illustrate in this application a complete machine.

By the use, of the term shifting in the following claims I mean the forward and the rearward movement of the plows with the relation to the frames as hereinbefore set forth.
